Installation
Do not install the unit where there is a risk
of leaking flammable gas.
If flammable gas accumulates around the
unit, it may ignite and cause a fire or explo-
sion.
To reduce the risk of injury from coming in
contact with units, install units where they
are not accessible to people other than
maintenance personnel.
Do not modify. Installation work must be
performed by the dealer or a qualified per-
sonnel in accordance with the instructions
in the installation manual. There is a risk of
water leaking, injury, electric shock, and
fire.
Dispose of the packing material. There is a
risk of an injury.
Destroy the packing material. There is a risk
of a suffocation accident.
All drainage work should be performed by
the dealer or qualified personnel according
to the instructions detailed in the Installa-
tion Manual. Improper drainage work may
cause water leakage and resultant damage
to the furnishings.
Do not install the unit over things that are
vulnerable to water damage. Provide an ad-
equate collective drainage system for the
drain water from unit as necessary.
To reduce the risk of damage to the unit and
resultant electric leak and electric shock,
keep small animals, snow, and rain water
from entering the unit by closing the gap in
the pipe and wire access holes.
To reduce the risk of rain water or drain wa-
ter from entering the room and damaging
the interior, drainage work must be per-
formed by your dealer or qualified person-
nel according to the instructions detailed in
the Installation Manual.
To reduce the risk of injury, products weigh-
ing 20 kg or more should be carried by two
or more people.
Remove packing materials from the unit be-
fore operating the unit. Note that some ac-
cessories may be taped to the unit. Properly
install all accessories that are required. Fail-
ing to remove the packing materials or fail-
ing to install required accessories may
result in refrigerant leakage, oxygen depri-
vation, smoke, or fire.
Consult your dealer and take appropriate
measures to safeguard against refrigerant
leakage and resultant oxygen starvation. An
installation of a refrigerant gas detector is
recommended.
Any additional parts must be installed by
the dealer or qualified personnel. Only use
the parts specified by Mitsubishi Electric.
Installation by unauthorized personnel or
use of unauthorized parts or accessories
may result in water leakage, electric shock,
or fire.
Take appropriate safety measures against
wind gusts and earthquakes to prevent the
unit from toppling over and causing injury.
To reduce the risk of injury from units falling
or falling over, install the unit on a surface
that is strong enough to support its weight.
